MADISON, Wis., April 9, 2014 /PRNewswire/ -- Retail natural gas base rates will be reduced and retail electric base rates will be unchanged for customers of Alliant Energy's Wisconsin utility if a request filed today with the Public Service Commission of Wisconsin (PSCW) is approved.

Alliant Energy is requesting retail natural gas customers' annual retail gas base rates be reduced by $5 million in 2015, followed by a freeze of those rates through 2016. For electric customers, retail electric base rates will remain at their current levels through 2016.

Alliant Energy's retail electric base rates have been stable since 2010 and retail natural gas base rates have decreased. This request to extend rate stability through 2016 includes input from Citizens Utility Board and the Wisconsin Industrial Energy Group.

"We currently have some of the lowest electric and gas rates in the state, while using renewable energy and reducing emissions," said John Larsen, President of Alliant Energy's Wisconsin utility. "This is especially welcome news for our customers who recently experienced one of the coldest winters in decades."

The PSCW approval process for the proposed retail electric and gas base rate freeze is expected to be completed in the second quarter of 2014. If approved, the base rate freeze proposal would become effective January 1, 2015 and extend until the end of 2016. The proposed terms of the freeze are similar to the January 1, 2013 through December 31, 2014 rate freeze currently in place.

The request recognizes the investments made in Alliant Energy's Wisconsin electric system, including:

Improvements in the environmental profile of Columbia Energy Center Units 1 and 2 and Edgewater Generating Station Unit 5

Continued investment in the electric and natural gas delivery system to maintain safe and reliable service

While electric base rates will not change under the Alliant Energy rate freeze proposal during 2015 and 2016, changes in fuel costs would be adjusted in customer bills during that time. Alliant Energy will file an annual electric fuel cost plan for calendar years 2015 and 2016. Fuel costs for natural gas customers will continue to adjust monthly as gas costs change.

Continuation of the earning sharing mechanism that is currently in place for 2013 and 2014

Common equity component of regulatory capital structure of 50.46% in 2015 and 50.95% in 2016

Retail electric and gas rate base of $2.5 billion in 2015 and $2.7 billion in 2016

Escrow treatment of major transmission charges

Continued use of the conservation escrow to offset rate base additions

The proposal must be approved by the PSCW before it becomes effective.

The proposal is available on the PSCW's electronic filing system. The filing is under Docket No. 6680-UR-119.
